Theatrical GMing and info dumps are mostly not useful in Blades as they tend to interfere with the recursive process, either via time (info dumps) or register (theatricality). Those things are great in other games sometimes, but not in Blades IMO. Pithy and provocative framing is a pretty succinct description of what GMing Blades should look like. You need the recursive process operating at high speeds to get the most out of the mechanics in Blades, so anything that runs counter to that is suboptimal, IMO.That all makes sense.
Let me ask you something (and this may seem like an odd question from viewers afar) - disconnected from player input and the table-facing dynamics which you went through above.
There is a lot of celebration of both elaborate world-building and theatricality + heavy exposition dumps in D&D culture and feel/immersion being downstream of that. If my GMing style was extremely theatrical with elaborate exposition dumps, would that have enhanced or detracted from all the things you mentioned above? What I'm asking is "does GMing with theatrical and elaborate exposition dumps vs pithy (both in terms of theatrics and word count) and provocative framing" have impact on (a) play broadly and (b) this kind of play specifically?
And how would players who are used to (and feel they are moved/compelled by) GMing with theatrical and elaborate exposition dumps in their framing feel about the different kind of framing that we're discussing here?
As I said above, a main ingredient that replaces those two things in a game of Blades is player activity and ownership of consequences. What that lacks is the element of being entertained that I think characterizes those two play elements, from the player side, obviously. I found initially with Blades, as would many people I suspect, that the game asks a lot more from the players than some other games. and that takes some getting used to and won't be to everyone's taste either.
